Here's what I tried:\r\n\r\n- `SEC(\"tp_bpf...`: the syscall tracepoints aren't available.\r\n- `int BPF_KPROBE(handle_do_sys_open, int dfd, const char __user *filename, int flags)`: I don't think the BPF_KPROBE macros are available properly outside of the selftests yet.\r\n- `PT_REGS_PARM2(ctx);`: needs uapi/linux/bpf.h, which is missing outside of the kernel source.\r\n\r\n@anakryiko any other ideas? Thanks.ghprbCommentBodynullghprbGhRepositoryiovisor/bccghprbCredentialsId6d3daf13-69b8-48b1-9c8f-ec5353264113false<a title="libbpf-tools: add CO-RE opensnoop" href="https://github.com/iovisor/bcc/pull/2778">PR #2778</a>: libbpf-tools: add CO-RE ope...#36416090977460664bcc-pr #364364false3642927FAILURE1583273866475https://buildbot.iovisor.org/jenkins/job/bcc-pr/364/git364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=fc25/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=fc26/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=fc27/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=fc28/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=ubuntu1604/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=ubuntu1710/364/364https://buildbot.iovisor.org/jenkins/job/bcc-pr/label=ubuntu1804/364/
